Researchers have developed a new type of pressure sensor - dubbed a "second skin" - which they say could prevent dangerous sores.
The technology is being developed initially for amputees who suffer rubbing against their artificial limbs.
If the Southampton University work is successful the sensors may also be used for others at risk, such as wheelchair-users and those confined to bed.
The sensor is thin and flexible like a small golden postage stamp. It is taped to a liner - essentially a cushioned sock - which is then placed in the socket connecting the stump and the artificial limb.
It sends that information to researchers and clinicians who can monitor the pressure peaks and troughs as the patient walks, and see if any adjustments are needed to prevent discomfort or pain.
Dr Liudi Jiang from the University of Southampton, who is leading the project, says the sensors could act as what she calls a "second skin".
She believes this technology may have many more uses which could prevent pain, infections and even amputations.
"This is a platform technology and we envisage it could be applicable in many other healthcare sectors such as smart shoe insoles for people with diabetes, or wheelchairs or mattresses - wherever the body rubs."
